Chapter 11 — Key Takeaways
One page. If you remember nothing else from this chapter, remember the three questions and the trend test.
The frame: three questions, and everything else is derivable
Underwriting asks the same three questions about every dollar a borrower receives, in order:
- Is it stable? Does it have a history? → produces every history-length rule (two years of overtime, two years of commission, six months of support received, two years in the same seasonal work).
- Is it likely to continue? Forward, commonly stated as a three-year expectation → produces the employer's continuance statement, the end date on an award letter, and the remaining-months count on a support order.
- Can it be documented? By a third party the underwriter will believe → produces the VOE, the W-2, the 4506-C, the transcript, and the exclusion of cash income no record supports.
Qualifying income is what survives all three. It is produced by the lender, not reported by the borrower.
The core rules
| Situation | Rule |
|---|---|
| Salary or fixed hourly | Current rate, never averaged. A raise counts immediately. |
| Bi-weekly pay | × 26 ÷ 12. Not × 2 — that understates by 7.69% every time. |
| Semi-monthly pay | × 24 ÷ 12, i.e. × 2. |
| Full-time hourly | rate × 2,080 ÷ 12 — but only if the VOE says 40 hours. |
| Overtime, bonus, shift differential, commission | Commonly a two-year history, averaged over 24 months. |
| Variable income RISING | Use the 24-month average (lower than the recent year). |
| Variable income DECLINING | Use the lower, most-recent figure (the average is not usable). |
| Rental income | Net, not gross. Gross × factor (commonly 75%) − PITIA. A negative result is a liability. |
| Non-taxable income | May be grossed up by a program-set percentage. Look it up every time. |
| Alimony / child support received | Documented receipt behind it; enough months remaining in front of it. |
| Part-time / second job | Commonly two years, uninterrupted. |
| Seasonal | Divide by 12, not by the months worked. |
| 1099 commission | Not this chapter — self-employed treatment (Ch. 32). |
Both branches of the trend test select the more conservative number. That is not two rules; it is one rule — the underwriter is forecasting, not auditing — applied to two shapes of data.
The key formulas
$$\text{24-month average} = \frac{\text{prior-prior year variable} + \text{prior year variable}}{24}$$
$$\text{monthly base (bi-weekly)} = \frac{\text{gross per period} \times 26}{12} \qquad \text{monthly base (hourly, full-time)} = \frac{\text{rate} \times 2{,}080}{12}$$
$$\text{YTD annualized} = \frac{\text{YTD gross}}{\text{periods elapsed}} \times \text{periods per year} \qquad \text{grossed-up} = \text{non-taxable} \times (1 + p)$$
The Linden Street income file — \$10,500.00, four components
| Component | Monthly | Rule |
|---|---|---|
| B1 base (RN, hourly) | \$5,720.00 | \$33.00 × 2,080 ÷ 12 — current rate | |
| B1 shift differential + overtime | \$580.00 | \$13,920 ÷ 24 — rising, so the average is usable | |
| B2 base (outside sales, salaried) | \$2,400.00 | \$28,800 ÷ 12 — current rate | |
| B2 commission | \$1,800.00 | \$43,200 ÷ 24 — rising 18.18%, so the average is usable | |
| Total | \$10,500.00 | housing 28.89% · back-end 42.66% |
The Fulton Avenue contrast: \$109,500 → \$107,000, a 2.3% decline. The 24-month average is \$9,020.83**; the most recent year is **\$8,916.67; the underwriter uses \$8,916.67. The accountant told the borrower "about \$9,500." (The mechanics behind those two numbers are Chapter 32's.)
Where deals die
- The bi-weekly × 2 error. On Linden Street it would drop income to \$10,060.00 and push the back-end ratio from 42.66% to 44.53% — an arithmetic mistake that looks exactly like a guideline problem.
- The day-40 verbal VOE. The borrower took a better job and told nobody, because nobody told them it mattered. Ask at application; ask again at day thirty; write the answer in the file.
- Averaging a declining stream. Down is down. There is no materiality threshold to argue past.
- Counting the second job that started ten months ago. Documentable, continuing, and still not qualifying income.
- Quoting a gross-up percentage from memory. For a file near a threshold, the percentage is the approval.

What you should be able to do Monday morning
Take a first call, and in twenty minutes produce a monthly qualifying income figure you can defend line by line — base at the current rate, every variable component averaged and trend-tested, every dollar tied to a document you have named and a rule you can state — and then tell the borrower, in plain language and before anyone writes an offer, exactly which parts of their pay the file counts, which parts it does not, and what would have to change for that to change.
